Bottlenose dolphin

It is a big and robust dolphin with approx. 4 metres of maximum length, showing a grey coloration in most of its body, despite the slightly darker dorsal area in comparison with the abdomen. It has a small beak, with each hemi-maxilla displaying 20-25 conic teeth, and a relatively big and curved dorsal fin. The diet of this mammal is composed of fish and cephalopods, with a habitat dispersion ranging from warm and temperate coastal, to oceanic and even estuarine waters. Occurs frequently along the whole Portuguese mainland coast, where a well-known and monitored resident population in the river Sado estuary can be highlighted. It is the most used species in captivity and in water parks around the world.
